Bricolage: bobine Tesla

Posted by

Voilà encore un petit kit sans prétention acheté chez Banggood (5€ livré chez vous) :

Comme à l’accoutumée, le colis arrive dans un petit sachet gris qui contient un sachet de composants et une notice en chinois.

Le QR code imprimé sur la notice nous amène à un document PDF 特斯拉线圈套件制作图文说明.PDF qui sera bien utile.

(Grâce à Google Translate nous apprenons que 特斯拉线圈套件制作图文说明 se prononce: “Tè sī lā xiànquān tàojiàn zhìzuò tú wén shuōmíng” et signifie: “Description graphique de la production du kit de bobines Tesla”)

       
 

Préparation des outils:

  • fer à souder et soudure
  • petite pince coupante
  • tournevis
  • bonus: pâte thermique pour les 2 semiconducteurs
  • bonus: pistolet à colle

 

Identifier les composants et leur polarité, mesurer les résistances en cas de doute.

Souder en commençant pas les plus résistants à la chaleur: connecteurs, résistances, condensateurs, transistors, LED et terminer avec la bobine.

 

        

    

Ci-dessus, on peut voir le très fin fil secondaire de la bobine, délicatement gratté pour pouvoir le souder

    

Pose du fil primaire (3 tours) pour terminer

Alimentation avec 9V sur piles pour un premier test à basse tension

Essai avec la petite lampe néon fournie avec le kit.

        

Avec 15 volts en entrée, la petite lumière bleutée au bout du fil est nettement visible, même en plein jour.

Problème: des arcs éléctriques se forment au contact des 3 spires du primaire avec la bobine du seondaire. Il va falloir un fil un peu plus long et éviter que ça ne se touche.

Voici avec une alimentation de 17,4V

Note: This is a DIY kit, you need to assemble it.

Feature:

 

The Tesla coil can produce high temperature and high-pressure plasma, which can sing, ignition, wireless transmission, and light fluorescent lamp. It has a wonderful arc. It is a very interesting small production of scientific experiments. This is a DIY Tesla coil Kit parts, which needs to be soldered and assembled by yourself.

 

Parameters:

 

  1. PCB size: 4.0mm*8.0mm
  2. Power: 15W
  3. Power input: DC 15-24V. The current is 2A. DC5.5 interface / pin
  4. Audio input: 3.5 socket, can be connected to mobile phone, MP3, computer audio

 

Principle introduction:

 

Tesla coil is a transformer that operates on resonance principle. It was invented by Nicola Tesla, a Serbia American scientist in 1891. It is mainly used to produce ultra high voltage, but low current, high-frequency AC power. The Tesla coil is composed of two groups of resonant circuits (sometimes three groups) coupled. The Tesla coil is difficult to define, and Nicola Tesla has tried a large number of configurations of various coils. Tesla uses these coils to carry out innovative experiments, such as electrical lighting, fluorescence spectrum, X ray, high frequency alternating current phenomenon, electrotherapy, and radio energy transmission, transmitting and receiving radio signals.

 

Tesla function:

 

  1. Electric arc function: the traverse of the rear end will produce an arc. The arc can also ignite.
  2. Septum light function: after the Tesla coil is electric, the fluorescent lamp can be lighted apart.
  3. Music playback function: a new concept loudspeaker for an electric arc to stimulate air to make air vibration produced by plasma. You can play mobile/computer music, but the sound is small.

 

Installation steps:

 

Tips:

 

  1. Install small components at first;
  2. Install complex components preferentially;
  3. Pay attention to the installation direction of components.
  4. Make sure the soldering iron does not touch the components for a long time. Otherwise it is easy to damage the components.

 

Note:

 

  1. This product is safe, power is not high, will not be injured by electric shock, but it is not recommended to touch the top of the coil arc, there will be a sense of burning.
  2. Do not touch the heat sink after a long time power supply, the temperature is very high, especially the use of 24v high voltage heat huge, if necessary, add their own cooling fan cooling, or working hours lead to too hot, please turn off for a period of time Electric use.
  3. Tesla coil is recommended to work when the body or other objects close to the coil, the coil next to half a meter blank can not be other objects, as other objects as a good conductor will make the coil form a good loop, absorbing the coil energy, making Testers Pull the coil at this time the effect of demonstration or deterioration can not be demonstrated!
  4. Do not put cell phones, mp3 and other electronic equipment close to the coil, or the coil will produce high-frequency magnetic field interference, making mobile phones, mp3, and other equipment failure or damage!

 

Note:

 

1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.

  1. Please allow slight deviation for the measurement data.
  2. Please allow 1cm-2cm error due to the hand measurement .
